Futuristic Cyberpunk Sentinel Triangle, Sentinel stands for Swift Equatorial Not Thinking Inverse Novice Evitable Linker, this long-distance kind of throwable nucleair device is superfast and can be thrown upside down or downside up, a blind apparatus that travels at least the distance to the equator, it does not care about the starting point, or has not the capacity to do so but before throwing you can set it to Link and then it will only propell to your target and let you know if it has found it. Great for playing boomerang with your mother-in-law if you keep 30.000 km distance from her and will be so generous to throw first
